- In this HVAC Training Video, I go over How to Replace a Stuck, Leaking, Schrader Valve Core with a Valve Core Removal Tool. Sometimes the Valve Core just does not want to come out and I wanted to share how I am able to get them out effectively without losing refrigerant, recovering, or pumping down the unit. I go over the process step by step during the replacement. Supervision is needed by a licensed HVACR Tech while doing this as Experience and Apprenticeship garners Wisdom and Safety.

It's nice to see a competent mechanic...Good job and clear explanation...:)
Thanks godbluffvdgg!
I just bought the blue soap, schrader valve cores and the appion valve core removal tool from your links at the bottom. I cant wait to try it out. Thanks for the video and tips!
I was using the Appion 5/16" core removal on a Daikin VRV III unit today, and I always have one that doesn't want to grab well. I remembered your "turn slowly and out" tip, and it worked great, so thanks for that tip!
Awesome, thanks tcpHVAC/R!
I wish I had seen this video years ago... I was using the de minimis "hole-shot" for years, until I figured out the "slow-turn" works almost every time. Great video, as usual.
Glad you enjoyed it Leo!
You're videos are fantastic, thank you
I’ve found a lot of times just loosening the connection to the service valve works. If it’s too tight the O ring inner diameter shrinks as it’s compressed and will hang up the core threads. If you loosen it it will relax and the core will be able to pass through. Then tighten it up for vacuum or recovery. Try and keep it as loose as possible without it leaking. Not that this is the case every time. Good vid.
Great Tips John, thanks!
John McMaster A1 to that
We have had that same experience. That if it's to tight it won't let it come out. So we barely put on the valve tool and and then go ahead and unscrew the valve core and let it pop out and then turn your valve and if the tool is not on tight enough you will then know and at that time you can just snug up the tool.
FROM CHICAGO THANK YOU SO MUCH I REALY LIKED THE WAY YOU SHOWED ON YOUR VIDEO
Was looking for this video,thanks for sharing.
Thanks NG TAI WEI!
I love your videos. Thanks for sharing your knowledge!
Thanks technolucas!
Thank you for helpful tricky method!
Thanks Tapch MC!
Excellent video. Thank you
Very helpful tutorial 👍
Always a great video👍
Thanks AC!
This is an important trick, I have done the same mistake as you have shown and very frustrated, thanks for this tutoring.
Also make sure that the rubber grommet is not squished too much otherwise it will squish against the valve core and cause it to fall off the rod when unscrewing it, thanks!
2:28 - I learned this thread trick years ago and it has saved much frustration in that time. You are the first mechanic I've ever seen that knows about this (or, at least said it out loud).
You didn't actually say it, although you demonstrated the turning of the thread slightly more (I usually use 1/2 turn.) For those who don't know, you can use this trick and its reverse for any thread of any type e.g., machine, sheet metal, pickle jar, milk jug, etc. The 'reverse' being: push the screw in until the top thread meets, then turn counterclockwise until the contact is felt or heard before turning clockwise to tighten. This will prevent (in all cases) cross-threading of the threaded part (lid or cap, screw, sheet metal or machine, etc.)
My old man taught me this. I use it regularly and it works every time
I’ve always done this. I just learned it myself. I can’t believe no one else does this in your field.
GREAT TOOL. THANKS
Huh that’s cool, thank you ACST
Thanks Cory!
good video instruction. thank you
Helpful video
thank you
Very helpful sir thank you
Good stuff.
Thanks very useful
Grate job amigo
Great tip! I’ll be trying this today. It’s so frustrating when the core doesn’t come all the way out.
Also try not tightening the tool on too much. It squishes the rubber oring inside and the valve core gets hung up on that, thanks Mike!
acservicetech I used to be guilty of over tightening all my connections until I started using nylog. Not chasing leaks nearly as much using that stuff.
Man wish i watched this earlier, this week, all 3 of my Appion had the same issue. Gonna give it a try 🤞
I wished I saw it earlier, I just figured it out then! thanks!
Also try not swishing the rubber grommet so much when connected to the port. That is also the holdup on the valve core, thanks!
I would think i would need to tighten down the port side especially on the HIGH SIDE due to higher psig of 410a. But i will definitely gonna try it.
Thank you 100000 time
Great tip!! Thanks!! ;)
Thanks Pedro!
Thanks.
Impressive
i've experienced Appion core tool works better than C&D. Good training video.
Thanks JD!
You had the EASY job! What really happened is the entire back of the stuck schrader valve broke off leaving the threaded part still in the valve body! Now THAT'S a real bitch problem! I ended up simply leaving the (cheap) valve removal tool on the system. ($16 compared to $450 to have the entire valve body cut out and replaced)
Yeah that really stinks, sorry to hear that, thanks!
There is an extractor attachment that connects to the YJ tool that will remove the broken core that remains in the valve body.
Your videos are great, very helpful. When are you coming out with a printed version of your book?
It will be soon but I will be sending out an update when they are ready, thanks!
Thx
No problem
Is this likely the issue if I'm not getting any reading on my gauge or release of gas when I manually press the core in?
Thank you for your videos and your help, i have a question could you please tell me the normal pressure on refrigerant 410 A
Thanks
Have a great day.
That will depend on the size of the unit, metering device, temp, humidity. You would need to check with superheat with piston and subcooling with txv. Check out the superheat and subcooling playlists, thanks
Great vid! Can you make videos on rooftop units?
Hey Aaron, are you talking larger packaged units or small systems and I just like to know what portion, cooling or heat? Thanks!
acservicetech yes packaged units, cooling and heating.
Thanks for your nice video.
Couldn't you back seat the service valve then change the valve core without using this too.
Thanks.
If the valve has a back seat position then it usually does not have a valve core. This type of valve has a front seat but no back seat, thanks!
@@acservicetechchannel
Thanks.
I wonder how common it is that when attempting to remove a gauge set that the schrader valve does not close properly? If that problem is anticipated perhaps it would be good to attach the gauge set to the tool initially incase there is a problem?
This way you could easily replace the valve. I'm assuming in the event there is a leak it would be small enough in most cases to remove the hose and then quickly put the tool on.
Have you ever used nylok on schrader valves?
Hi just a question appion core removal vs yellow jacket witch one do you think is the best for the Jobe
Thank you
Ziyad toronto
In my opinion, the appion ones seem to be the best for vacuums and recoveries.
Wish I saw this a few weeks ago
Yeah and during recovery and vacuum , have the tool snug so the rubber O-ring has a tight seal but when replacing the valve core, loosen the tool up a little to where it is not leaking but the O-ring is not as squished, thanks!
Thanks for the tips. Does you channel have any videos on residential boilers?
Seems like we should be able to just swap this to a ball valve after removing the schrader. But the tool has the port on the wrong side I believe.
HI, need your advice - When pulling a vacuum in a heat pump, with the schrader valve removed i am able to pull only down to 2000 microns. I then insert the schrader valve and start pulling and this time i am able to pull down to 400 microns. This sort of completely opposes the theory of pulling a vacuum with the schrader valve removed. Can you please explain this phenomenon and where I am wrong? Thanks in advance.
Should I replace all the schrader valves, including both high and low pressure ports at one time ?
By the way, what is the size of these 2 ports ? 1/4 or 5/16 ?
You can replace them individually, 1/4" usually for split systems and 1/4" or 5/16" for minisplits. I have the 1/4" and 5/16" valve core removal tools linked at amazon.com/shop/acservicetech, thanks!
Hey bud , I have a resto 557 manifold and has the external micron gauge that comes with it and manifold provided micron reading. Are those trustworthy? I feel like every time I pull a vacuum microns climb a bit even though I did a proper leak check. I’m starting to think I need a different gauge.
Look up "acservicetech full vacuum procedure" it is best to keep that manifold off the vacuum. Then no hoses are involved during the standing vacuum test. This video shows the whole procedure, thanks
I have the C&D remover from a year ago. What a pos it was! Ive tried everything similar to your technique but the core refused to come out. Ive stopped using it for a long time now..
Oh wow, a lot of people would rave about using the C&D valve core remover for replacing stuck cores. Sorry to hear that!
Hi mate do we need to remove the core when we vacum a new split system?
Yis.
Otherwise the evacuation will take forever.
Mine still leaked.
So/the supply folks sold me a new cap and gasket plus thread tight.
It's a fast leak/I can feel and hear it.What have I done wrong?
👍🏾👍🏾👍🏾👍🏾👍🏾
Thanks Tank!
How would you remove a schrader valve core if it is broken? The head came apart from the base that screws in.
If you do a pump down can you change schrader valves without losing refrigerant?Thanks
Hey Chad, do you mean can you change the valve cores after the pump down is complete? Yes if the pressure is behind the service valves, then in front where you are reading the 0 pressure through the valves would show that there is no pressure if I am understanding what you are asking, thanks
@@acservicetechchannel ok i see what your saying,when the gauges say zero,then the pressure is behind the closed valves,so I can change scraders,thanks,keep up vids,learning alot
Yes then vacuum again, thanks
my schrader core is lose and it won't come out, I believe the core's center pin is slightly crooked..not fitting into tools center hole. Any advise how to get it out?..
I just put a video out on that- czcams.com/video/3KaJytmG5OM/video.html
whats the best valve core remover tool for r134a?
I would still use this one. The refrigerant and oil would not be a deciding factor as long as the unit was an HVACR unit. If it was for a car then you would be talking a different tool, thanks Richard
Here is the link to the Appion Valve Core Removal Tool- amzn.to/2uYr8WL
how often do you have to replace valve cores?
You shouldn't have to unless the cores are leaking or doing work on the unit where you are bringing the pressure to 0psig and just replacing because they are old, thanks Walt!
I took out the valve I put a new one but he didn't want to enter
The front grommet of the valve core removal tool is probably too tight onto the port and squishing the grommet which would close off the inside of the tool, thanks!
I think I'll GO AHEAD and watch this video....then I'll GO AHEAD and add this comment.
If you use the Hilmor removal tool you won’t have to deal with stuck valves!
Heads up, new Hilmor core tools require some hvac type lube to work smoothly during break in.
You won’t find a tool that grabs better!
Thanks Richard!
But this video is not how to remove a stuck core, it is just how to remove any core. The core in this video is not stuck.
